Patent DE-2226715-A1 (DE)
Title: Pyrotechnical article - protected against effects of temp variation
IPC: F42B12/76
Filed: 1972-06-02
Abstract: Device eliminates the effects of changes in temp. on the strength of a casting in a pyrotechnical article, (e.g tracer ammunition), whose casing, (e.g. comprising MgO in combination with epoxy resin), ensures that the article burns from its end in a controlled, fashion. The casing contains material which lowers its thermal expansion coefficient to that identical to the article. Stresses in the casing are avoided allowing the article to be stored in places subject to wide changes of temp.

Abstract: 1430164 Porous ion-exchanging shaped articles BASF AG 1 Aug 1973 [2 Aug 1972] 36519/73 Headings C3C and C3P Porous ion-exchanging shaped articles are prepared by mixing (1) a particulate cross-linked polymer obtained by dispersion polymerization of styrene, a styrene derivative of acenaphthylene in the presence of 1 to 20 weight per cent of an aromatic divinyl compound and (2) an olefin polymer in the presence of (3) an inert organic liquid of low volatility, forming the mixture into shaped articles and introducing ion-exchange groups into the mixture after shaping the inert liquid being removed after shaping. The crosslinked polymer may be derived from styrene, methyl styrene, acenaphthylene or a mixture of styrene with methyl styrene, stilbene or acenaphthylene, together with divinyl benzene; and may be mixed with a polymer of a C 2-6  olefin. The mixture may be formed into fibres, fabrics or membranes and ion-exchanging groups introduced by sulphonation or by chloromethylation and amination. The inert liquid may be tetralin, decalin, anthracene, acenaphthene, diphenyl, C 10-40  alkanes, adipate or phthalate esters, camphor or oleic, stearic or palmitic acid. After shaping it may be extracted, e.g. with methanol, acetone or light naphtha to give microporous articles. In examples (1) cross-linked polystyrene is mixed with polyethylene in tetralin and after shaping into fibres the tetralin is extracted with boiling methanol and ion-exchange groups are introduced by sulphonation, (2) cross-linked polystyrene is mixed with polypropylene in paraffin oil and after shaping into fibres the paraffin oil is extracted with boiling acetone and ion-exchange groups are introduced by sulphonation, and (3) fibres as in (2) are chloromethylated and aminated.

Abstract: The control system for the spin drying phase of a washing machine has a time clock and switching circuit in the programme control to the drive motor, so that the motor is driven rapidly in intermittent pulses and does not reach a continuous top speed. The drum is driven rapidly , but does not develop a ring wall of water round the drum inner surface, allowing the extracted water to flow through the perforated drum easily, reducing the load on the drive motor and allowing the use of a small motor.
Patent DE-2449115-A1 (DE)
Title: Method of taking up torque exerted during descaling - by deforming the material before clamping
Inventor: LINDEMANN HANS
IPC: B23B5/12
Filed: 1974-10-15
Abstract: The method allows material to be clamped at high infeed speeds during descaling. The section of the rod material is deformed so that it is no longer circular. The deformed section which is square or triangular can be easily secured in a clamp against any torque practically up to the shearing point. If the material is wire which is to be unrolled and rolled up again, the deformed section is obtained by rollers or by means of a drawing die. The deformed material is restored to its original shape before the descaling arrangement.

Title: Chipboard of various thicknesses - made from dried ligno-cellulosic pieces by sequentially fractionating bunkering discharging glueing and depositing
IPC: B27N3/14
Filed: 1975-02-11
Abstract: Mfr. of chipboard or similar prods. ranging from relatively great to small board thickness, comprises sequentially subjecting dried, ligno-cellulosic, particles to fractionation and then bunkering, discharging and glueing, after which the so-obtd. inter. prod. is deposited onto a moving support so that a fleece is formed which may finally by compressed into the intended board. Specif. when prodn. is switched from relatively thin to relatively thick boards then a portion of the material forming the top layers is combined, before forming the fleece, with the chip matl. used in forming the core layer. The claimed process ensures correct apportionment of suitable size range of chips used to the individual layers i.e. finer particles for outer layers, coarser chips for core layers; the proportion of finer chips being greater in relatively thin boards. Sieves for classification have to be a changed less often that in prior-art processes.
Patent DE-2507190-A1 (DE)
Title: Appts. for sepn. of oil mixts. with other liqs. - e.g. bilge-water from ships, using gravitational sepn.
Inventor: GRANTZ SIEGFRIED DIPL ING DR I
IPC: B01D17/02
Filed: 1975-02-20
Abstract: Appts. for sepn. of oil from mixts. with other liqs. consists of a cylindrical coarse separator into which the mixt. flows tangentially, a space above the coars separator for collection of sepd. oil, a fine separator below coarse separator and sepd. from it by a dividing plate, into one side of which fine separator the midt. flows, passing along its wall. The inner space of fine separator is divided by a number of conical plates sloping downwards and located one above the other. The upward-flowing sepd. oil flows along the under-surfaces of conical plates through openings into riser-pipe which is concentrically located and which extends upwards above fine separator. The heavier liq. sepd. from the oil is collected on the side of fine separator opposite to that on which the inlet is located, and an outlet pipe is fitted low down on outlet side. According to the novelty, the upper (outlet) end of riser terminates in coarse separator at such a distance below oil outlet that entrainment of the oil flow out of riser by inflowing mixt. in coarse separator is prevented. A non-return-valve is located at the upper end of riser whose weight is such that the resistance to opening is approx. equal to the prodt. of the discharge area and the specific gravity of the liq. to be sepd. Prevention of re-entrainment of oil into incoming mixt. enables separator to operate at higher throughputs.

Title: Multi-layer cutting tool production - uses several layers made of different steels bonded together to form the tool
Inventor: WEBER GUENTER
IPC: B23K31/02
Filed: 1975-02-25
Abstract: The actual cutting parts of the tool are made from ledeburitic chrome steels or high speed tool steels. All the layers are metallically bonded together by pressure welding with the exclusion of binders and fluxes. During the first deformation process a thickness reduction of more than 20% is attained. The various strips of steel laid out in the rolling direction are welded to the base and the rolling is conducted until at least a smooth surface is attained after which the plate is split. The spacing of the strips is chosen to give complete embedding in the material.
